Analyze_This

okay here is what i do, first i write any rates no matter how they are given in the mathmaticly correct way. a/b, you might not see it now, but one day you will realise it makes things much easier

2.20279 CHF/GBP
1.62699 USD/GBP
1.2755 CHF/USD

now it is kind of hard to see it here because the "/" sign should be a flat line, but no such charachter exists in ASCII code lol...but if you look at the last two rater you can see that you can cancel out the USD from both and end up with CHF/GBP by simply multiplying them

just put them next to each other and see

so, 1.62699*1.2755=2.07522

which is clearly not = to 2.20279

so there is arbitrage

someone out there, as indicated by the exchange rates you gave me is willing to pay 2.20279 CHF for each GBP

but by jumping from currency to another, i can end up buying 1 GBO for 2.07522 and selling it to him for 2.20279, instant profit

to do that, i would start with 2.07522 CHF, i would convert them to 1.626 USD
then i would convert that to 1 GBP

and i would sell it to some fool for 2.20 CHF....

----------------------------------------------------------------------

to sum it up, if you are looking for some shorcut, there is not, or at least i am not the guy to teach it to you

but all this is, math and logic and arbitrage...

with practice, you WILL get it

just look at the rates and start thinking, how can I make instant money, it would get more complicated when you involve bids and asks, but the concept is the same, try to understand this, and when you do maybe we try one with bid and ask ....
